[filmstrip @ 003fe580] only AV_PIX_FMT_RGBA is supported

This error message tries to tell you to use -pix_fmt rgba
Please understand that this is a bug tracker, not a support forum.

[str]

I know that this is the bug tracker. And I think, that if the encoder does not contains such information, then this is a bug. Most other encoders provide that information in their pix_fmts field. But this field is 0 in the encoder. The check is performed anywehere in the code but is not visible to outside.

[Carl Eugen Hoyos]

The rawvideo encoder supports not only rgba but all colour spaces.
The filmstrip muxer avoids to write invalid files.

[str]

And there is no way to check this programmatically? I use the API, not ffmpeg as tool.

[Carl Eugen Hoyos]

How do you choose filmstrip?
What I mean is: If filmstrip is hard coded, you can also hard code rgba or do I misunderstand?

[str]

In my app the user can select any muxers (by file extension). So I should have to hardcode each exceptional format or codec?
